Abstract
Robots are expected to join in not only a great success in the industrial field but a public and a home places. However, in order to accept robots socially, when our life spaces are shared with them, it is essential that a safety is fully obtainable. In this paper, for the development of a safety biped robot, new design concept is created by applying the contradiction solving method. Moreover, demands of a safety for this robot are solved not as "Problem Solving by Trade-Off", but as "Contradiction Solving". Therefore, we suggested new solution for contradict problems by using creative thinking process.
